CARBU RETING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 494,442, dated March28, 1893. Application filed April 13, 1891. Serial No. 388,812. (Nomodel.)

To wZZ whom it may concern:

Be it known that 1, JOHN RUTHVEN, of the city of Topeka, in the countyof Shawnee and State of Kansas, have invented a new and usefulImprovement in Oarbureting Apparatus, which improvement is fully setforth in the following specification and accompanying drawings, inwhich- Figure 1 is a perspective of the apparatus embodying myinvention. Fig. 2 is an end view of the same with the cooking attachmentclosed; and Fig. 3 is a view with the front portion removed showing theinterior. Fig. 4 is a similar view, showing a carburetor in connectiontherewith.

The invention relates to that class of cooking, heating and lightingapparatus, wherein hydrocarbon vapor is produced by suction from acarburetor outside of the building, underground. The vapor so producedenters the casing and is conveyed to a purifying chamber, after leavingwhich it is led to the cooking, heating, and lighting devices. Aregister is also provided to measure the number of revolutions of thesuction cylinder and the consequent amount of vapor used.

The invention consists in the novel construction and combination ofparts as-hereinafter specified.

In the drawings, the letter A designates a case or closure, havingtherein a water space or chamber I. In the upper portion of this chamberis a suction cylinder J carried by a shaft '12, said shaft havingbearings at one end in the wall of the case, and at the other end in anL-pipe or coupling pipe section H. The case is usually provided with anornamental upper portion X, under which is the top plate proper of thecase, and which is arranged so that the interior chamber is perfectlyair and gas tight.

N designates a pipe connected at one end to the coupling H, and passingdown outside of the casing to the lower portion of the water chamber,where it enters a purifying and drying chamber V. This chamber isdivided into compartments, E,E, &c., which are nearly filled withdifferent absorbent and purifying material, such as cotton,indicated atO, and charcoalshown at D.

C designates the'driving gear on the end of the spindle n, and which isoperated by a spring or weight (not shown) or by any other suitablepower. The rotation of this cylinder J causes a current of air to bedrawn into the carburetor y (which is outside of the building, and11nderground),through an air-supply pipe y leading thereto. The airpasses through the hydro-carbon fluid in the carburetor to the oppositeend of same, and becoming charged with hydrocarbon vapor enters theoutlet pipe and is conducted to an inlet M at the upper portion of thecasing. The water chamberI is filled, so as to submerge the purifyingchamber V, and partially submerge the cylinder J. Should a leak occur inthe chamber V, the water will enter therein, checking the escape ofvapor, and thereby prevents any opportunity for the same to beimproperly ignited. From the upper portion of chamber I, the vaporenters the coupling or pipe section H, the entrance of which is slightlyabove the axis of the cylinder I, and is conveyed through the pipe N tothe chamber V, which it enters in a saturated and heavy state. A cock 0is provided in the pipe N to regulate the flow. Escaping from the pipe Ninto the chamber V, it passes through the compartments E, E, &c., bymeans of perforations 0, 0, formed in the walls thereof, and is carriedoff in a purified state by the pipe E.

R designates a register which is a connectionwith the gear of the shaftn, to record the number of revolutions of the cylinder and theconsequent amount of gas produced. As each apparatus is provided withthis register, it is evident that several may be connected to the samecarburetor, and the amount used by each will be recorded.

Q designates a swinging cooking attachment, having a hinged connectionwith the forward portion of the case, and arranged to swing outwardlytherefrom into the position shown in Fig. 1. This attachment is providedwith a pipe having a series of burners c, c, &c., and which is suppliedwith gas by a branch from the pipe E, said branch being flexible, orprovided with a flexible section to permit the attachment Q to be openedand closed. Or said branch may be rigid and provided with a detachablecoupling.

P is the cooking table, having a hinged or swinging support, and locatedover the burners c. B designates a plate or wing having a similarsupport and arranged to check and carry all smoke and odors of cookingto a flue '1 at the back. To this flue may be connected a flexible pipe(not shown) for carrying off such odors and smoke.

Y is a swinging table under the burners, which serves to catch the drip'from any article being cooked, or on which dishes or any other articlemay be placed. These tables B, P, and Y are designed to fold back intothe frame Q when not in use, and said frame is then swung or closedagainst the case A, in the position shown in Fig. 2.

In the upper and lower portions of the case A are drawers K and L inwhich cooking utensils and dishes may be stored.

If desired a lamp may be placed on the up per portion of the case andsupplied with gas by a branch from the pipe E. The water in the chamberI may be drawn off by means of a faucet F.

In my former patent, No. 234,108, is set forth a device similar in somerespects to that above described, and I disclaim in the presentapplication, the construction set forth in said patent. The presentinvention differs from the former patent, howeverin several importantfeatures. In the first place, the carburetor is located externally ofthe case, and is connected with the fan chamber, by a pipe through whichthe vaporized air is drawn in to the case. The carburetor is preferablyexterior to the building. This arrangement is more desirable thaninclosing the carburetor in the case. In the second place, I provide thecase with a cooking attachment, which when closed, forms one sidethereof, and the burners of which are supplied by a connection with thepurifying chamber within. The arrangement and construction of the caseis different from that of the former patent.

Having described this invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination with a case or closure A, having therein an air-tightchamber I, a suction fan operating in the upper portion of said chamber,a submerged drying and purifying chamber in the lower portion of saidchamber I, and a pipe leading from the upper portion of said chamber Ito said drying and purifying chamber, and from said chamber to theburners, of a carburetor located exterior to the building in which saidcase or cabinet is situated, an air-inlet pipe for said carburetor, anda pipe connecting said carburetor with the upper portion of said chamber1, substantially as specified.
